SLink card for SQ series mixers

SQ SLink provides engineers with the option to add an additional intelligent SLink port to any SQ console. With the same functionality as the built-in SLink port, the card allows connection to a further 128 inputs and 128 outputs of digital audio and opens the SQ to a range of new system possibilities.

The option card runs independently from the built-in SLink port, allowing two different Allen & Heath protocols to be used in one system, at the same time. With two SLink ports it’s now possible to combine an SQ with any ME personal monitoring system, DX (96kHz) or dSnake (48kHz) expander.

Any SQ console fitted with an SLink card can also now be directly connected to another Qu, SQ or dLive system, further extending the system’s expansion and potential for digital FOH / monitor splits, broadcast feeds and more.



  • 128 inputs and 128 outputs of audio and preamp control
  • 96kHz or 48kHz operation
  • gigaACE (96kHz), DX (96kHz) or dSnake (48kHz) connectivity
  • Intelligent switching between modes
  • Independent SRC for use of two different protocols in one system
  • Plug’n’play installation*


*Note: The SLink card requires SQ firmware V1.3 or later.



New Possibilities

The new SQ SLink option card opens the SQ series to a range of new system possibilities:

SLink card using all protocols

SLink card and dLive using gigaACE

SLink with DX and ME
